Pelargonium plant named ‘Pacsamara’

ABSTRACT

A new and distinct Zonal Geranium plant named ‘Pacsamara’, characterized by its upright and uniformly rounded plant habit; moderate vigorous growth habit; freely basal branching habit; dark green-colored leaves; early and freely flowering habit; and red-colored semi-double flowers that are held above the foliar plane on strong peduncles.

Botanical designation: Pelargonium x hortorum.

Cultivar denomination: ‘PACSAMARA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Zonal Geranium plant, botanically known as Pelargonium x hortorum, and hereinafter referred to by the cultivar name ‘Pacsamara’.

The new Zonal Geranium plant is a product of a planned breeding program conducted by the Inventor in Dresden, Germany. The objective of the breeding program is to develop new uniform and early-flowering Zonal Geranium plants with dark green-colored leaves and numerous attractive flowers.

The new Zonal Geranium plant originated from a cross-pollination made by the Inventor of two unidentified proprietary selections of Pelargonium x hortorum, not patented, during the summer of 2016. Seed was collected from a number of potential parent plants, combined and sown. The new Zonal Geranium plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated mass cross-pollination in a controlled greenhouse environment in Dresden, Germany during the summer of 2017.

Asexual reproduction of the new Zonal Geranium plant by vegetative terminal cuttings in a controlled greenhouse environment in Dresden, Germany since January, 2018 has shown that the unique features of this new Zonal Geranium plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Zonal Geranium have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Pacsamara’. These characteristics in combination distinguish ‘Pacsamara’ as a new and distinct Zonal Geranium plant:

-   -   1. Upright and uniformly rounded plant habit.     -   2. Moderate vigorous growth habit.     -   3. Freely basal branching habit.     -   4. Dark green-colored leaves.     -   5. Early and freely flowering habit.     -   6. Red-colored semi-double flowers that are held above the         foliar plane on strong peduncles.

Plants of the new Zonal Geranium can be compared to plants of the Pelargonium x hortorum ‘Pacabel’, disclosed in U.S. Plant Pat. No. 22,881. In side-by-side comparisons, plants of the new Zonal Geranium differ from plants of ‘Pacabel’ in the following characteristics:

-   -   1. Plants of the new Zonal Geranium are more freely branching         than plants of ‘Pacabel’.     -   2. Leaves of plants of the new Zonal Geranium are lighter green         than leaves of plants of ‘Pacabel’.     -   3. Peduncles of plants of the new Zonal Geranium are medium         green in color whereas peduncles of plant of ‘Pacabel’ are         greyish brown in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Zonal Geranium plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Zonal Geranium plant. The photograph is a side perspective view of a typical flowering plant of ‘Pacsamara’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in 19-cm containers during the spring, summer and autumn in a glass-covered greenhouse in Dresden, Germany and under cultural practices typical of commercial Zonal Geranium production. During the production of the plants, day temperatures averaged 18° C., night temperatures averaged 16° C. and light levels ranged from 15 klux to 100 klux. Plants were four months old when the photograph was taken and nine months old when the detailed description was taken. In the following detailed description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
